REPRODUCING APPARATUS.

Application filed November 15, 1926, Serial No. 147,171, and in FranceFebruary 24, 1926.

This invention relates to a reproducing apparatus and more particularlyto an apparatus whereby a design, print, pattern or similar article maybe reproduced in any ratio and has for'its primary ob ectto accomplishthis result in a very accurate manner with mechanism mechanically ormanually operated.

An object ,of the invent-ion is the provision of mechanism of such adesign that the master device or controller can be located at anydistance necessary from the reproducing device.

Another object of the invention is the novel arrangement of the variousparts so as to simplify the apparatus without n any way affecting itsaccuracy of reproduction.

A feature of our invention is the novel construction of the controlmechanism whereby the apparatus may be operated continuouslymechanically or may be operated by hand.

With these and other objects in view the invention will be betterunderstood from the attached drawings taken in consideration with theannexed specification, wherein Figure 1 is a front elevation of thereproducing apparatus,

I Figure 2 is an end elevation of the master design holding frame,

Figure 3 and Figure 4 are detail views,

Figure 5 is a vertical sectional view of the reproducing frame,

Figure 6 is a front elevation of the reproducing frame having mechanicalmeans connected thereto for automatically controlling the air brush orthe like, and

Figures 7 and 8 are detail views thereof.

Referring now more particularly to the drawings wherein like andcorresponding parts are designated by similar reference charactersthrough the several views, the numeral 1 indicates the master designframe which has mounted upon ,one face thereof a print or other patternsheet 2 upon which is displayed the master design to be copied orenlarged upon the sheet or roll of paper 25 of the reproducing frame 12.These frames are connected by a lower channel bar or track 1 and a track2 is secured to the upper end of each frame in which travel the rollersof the carriages 3 and 13 so that the latter may travel across theframes. The carriage 3 has connected thereto a cable or sprocket chain 4which travels over the rollers 21 and 23 and a suitable handle (notoperated by the handle.

shown) may be connected to the roller 23 whereby this carriage may bemanually caused to move across the master design carried by the frame 1.Slidably mounted on this carriage is a follower (S carrying the tracerT. This follower is moved along the carriage by the chain or cable 8operated by the worm wheel '9 that engages the worm 10 on the shaft 11.The worm 10 is connected to the shaft to slide therealong but held inits engagement with the worm wheel 9 so as to actuate the sameirrespective of the position of the carriage 3 and tracer 7.

As the tracer T is moved over the design, print or similar article, themovement thereof is simultaneously transmitted to the proper apparatusto bring about a reproduction upon the sheet 25 positioned upon theframe 12. The carriage 13 of this frame 12 has a support or slide 14slidably mounted thereon to which is connected the opposite ends of acable 17 which passes over the roller 18 carried by the carriage 13. Theshaft 11 has also keyed thereto, but slidably thereon a worm gear 19which is operatively connected to the lower roller 18 whereby withrotation of the shaft 11 by moving the tracer 7 the support M will alsobe caused to move in a vertical direction over the sheet 25 due to thecable connection 17. The support 1 1 carries an air brush of thespraying apparatus 16. The air brush mayconsist of a plurality ofnozzles 15 as is illustrated in 3 whereby the designs, decorations,placards and the like may be reproduced in various colors. Thus it willbe seen that these connections are such that accurate reproduction isassured. The carriage 13 is moved in a horizontal direction by thesprocket chain 20 connected thereto and which extends over the sprocketwheels 21 and-21. One of the sprocket wheels 21 is connected to the heretofore mentioned chain I} which is manually Upon operation of this crankhandle and sprocket 23 connected thereto the chains at and 20 will beoperated for moving the carriages 3 and 13 horizontally and in unison.The relative speed of the carriages is determined by the relative sizeof the sprocket wheels. A crank handle may be a tached to the shaft 11to turn the shaft and thereby the slide 14 and tracer 7 through the wormwheel, sprocket and chain connection previously described. As far as wehave proceeded it will be seen that through the manipulation .of thehandles the tracer can be accurately moved over the design, and becauseof the positive mechanical connections the nozzle 1.5 moves in any rationecessary.

In Figure 5 we have shown in a diagrammatic manner, an arrangementwhereby a continuous strip of paper may be passed to view, and a designproduced thereon and subsequently removed. The strip 26 is passed oversuitably placed rollers 27' to provide a vertical set of drying folds 8and a horizontal set of folds that are positioned in a pan 29 so as tobe subject to a cleaning solution. A section 25 of the strip passes overthe heretofore described reproducing device so as to be worked upon bythe nozzle 15.

The remaining figures illustrate a possible way of mechanicallyoperating the reproducer. Herein, duplex carriages 26 and 27 are mountedfor relative horizontal and vertical movements upon the frame 12 andconnected by a suitable air brush support 28.

Suitably attached to carriage '26 is an endless cable or chain 37mounted to extend longitudinally across the frame 12 and passing over adrum which upon rotation, will cause carriage 26 to move horizontally.Likewise, fastened to carriage 27 is a cable or chain 30 riding onpulleys 30 carried by the upper edge of the frame 12. The free portionof the cable 30 is adapted to wind on a drum 31 freely mounted 'on thesame shaft supporting the first mentioned drum 35, and causing thecarriage 27 secured to brush support 28 to move vertically on frame 12which movement may be rendered smooth and uniform by counterbalancingthe carriage 27 as shown at 29.

ltigidly secured to the drums 31 and 35 are pinions 33 each meshing withindependent racks 42 and 13 respectively. The movement of these rackscause the different drums to rotate, transmitting, as stated before, ahorizontal movement to carriage 26 and a-vertical movement to carriage27. With a view towards affording a mechanical actuation of racks 42 and43 we provide a rotatable shiftable controller 40, having on itsperipheral surface two distinct and independent sets of spiral groovesdesignated by numerals 42 and 13 respectively, and whose surfaces areformed of a series of elevations and depressions registering the designor script to be reproduced, as more clearly shown in Figure 8;

The controller 10 is positioned so that the set of spiral grooves 42will receive the lower end of rack 42, while the set of grooves willreceive the lower end of rack 43. A counterweight 4:5 is arranged asshown at 32 to properly hold the racks in close engagement with theirregular surfaces of the double spiral grooves assuring an accuratereproduction.

In the'rot-ation of'the controller the racks will move up and down togive movement to the drums 31 and drum 35. The drum 31 will act on cable30 to raise and lower carriage 27 while drum 35 will act to operate thechain 37 which in turn will move carriage 26. Thus, it will be seenthatthe entire surface of the sheet of paper may be acted upon.

It is of course to e understood that there are many other forms of ourinvention and the various parts may be constructed in various other waysand connected in other combinations and therefore we do not desire to belimited in any way except as set forth in the following claims.
